LOOM.

Specification of Letters `IEatent No. 12,593, dated March 27, 1855.

To all 'whomzt may @cacem 1 `Be it known that I, DAVID S. HARRIS, yof

Coventry, in the countyof Kent and State of RhodeIsland, have invented anew and useful Improvement in Shuttle-Guards for Power-Looms; and I do hereby declare that the following is a full,clear, and eXact de scription of the same; reference being had to lthe accompanyingdrawings, forming part of this specification, in whichfd Figure 1, is a front view of the frame and lay of a power `loom `with my invention applied, and Fig.2,` is aside view of the same. y Similar letters off reference indicate corresponding parts in beth` figures.

. This invention "consists in the connection i i of the shuttle guard withthe belt shipper in such a manner thatthe shuttle guard is in its operative positiononly while the loom is in gear, and when the loom is out of gear the guard is raised soasto be out of the way oftheattendant whilepicking out, ordrawing threads through the reed. e

` A, A, arerthe side frames of the loom.

B is the breast beam, and C, the lower front rail, both of which are represented as partly broken away in Fig. l, toexpose the connections between the shuttle guard and the beltshipper.`

D,` isthe `shuttle guard consisting of a 1 light iron rod secured `to the lay "cap b, by two staples c, u@which serve as bearings.

i i. This rod cranked at a, a, to throwit for ward over the 'shuttle race to enable it to lay `over the `shuttle las shownin Fig. 2, and the end `nearest the shipper isbent l backwards overthe` layA cap toform an arm` d, to be connected by a light connecting ro e, with the longer armi at a lever f, which y works on afiXed fulcruIn g, in a stand E, on or near the licor. `Theshorter arm of the lever f, isslotted to receive a pin h, which is fast on an arm z', secured to the arbor y', of the shipper E. y

When the loom is in gear the guard lays over `the shuttle race in such a position that the shuttle passes between it and the reed and can not possibly escape from the loom, but when the belt is unshipped the arm z', is thrown towards the loom, carrying the shorter arm of the lever f, in the `same direction and throwing down the longer arm,

which draws with it the connecting rod e, and the arm of'the shuttle guard raising the `shuttle guardas shown in red outline in Fig. 2.

I do not claim` the`shuttle guard as I am aware the shuttle guards substantially simn ilar `to `that I haveshown 4have been elnployed attached fixedly to the lay, or if movable requiring to be moved by hand.k

And I do not @Online myself to the use of a y shuttle guard constructed precisely like that described; but

What I` claim as my invention and desire to secure by Letters Patent is-d y The connection of the shuttle guard in any way substantially as described with the belt shipper in such a manner that when the looni is in gear the guard may stand over the shuttle race in such a way as to prevent the shuttle flying out of the loom, but when the loom is out o-f gear the guard may be raised out off the way of the attendant, to enable threads to be picked out or drawn through the reed 0r such other manipulations to be performed as may be necessary.
